# Every item has a default value besides MIRRORS (which is unset).

# Use aptitude, apt-get, or apt?
# Note that apt-get is used as a fallback for outputting the
# package URI list for e.g. aptitude, which can't do this
# Optionally add the FULLPATH to apt-get or apt-rpm or aptitude
# e.g. /usr/bin/aptitude
#
# Default: apt-get

_APTMGR=/usr/bin/apt

# Default: dialog enabled

# Choose mirror list to speed up downloads from same archive. To select some
# mirrors take a look at your distribution's archive mirror lists.
# Debian: http://www.debian.org/mirror/list
# Ubuntu: https://launchpad.net/ubuntu/+archivemirrors
#
# It is required to add mirrors in the sources.list to this array as well, so
# apt-fast can destinguish between different distributions.
#
# Examples:
#
# Different distributions (as in operating systems):
#
# sources.list:
# deb http://deb.debian.org/debian/ unstable main non-free contrib
# deb http://de.archive.ubuntu.com/ubuntu/ bionic main universe
#
# apt-fast.conf:
# MIRRORS=( 'http://deb.debian.org/debian','http://ftp.debian.org/debian,http://ftp2.de.debian.org/debian,http://ftp.de.debian.org/debian,ftp://ftp.uni-kl.de/debian'
#           'http://archive.ubuntu.com/ubuntu,http://de.archive.ubuntu.com/ubuntu,http://ftp.halifax.rwth-aachen.de/ubuntu,http://ftp.uni-kl.de/pub/linux/ubuntu,http://mirror.informatik.uni-mannheim.de/pub/linux/distributions/ubuntu/' )

# Single distribution:

# Default: disabled

# Maximum number of connections
# You can use this value in _DOWNLOADER command. Escape with \${}: \${_MAXNUM}
#
# Default: 5
#
_MAXNUM=16


# Maximum number of connections per server
# Default: 10
#
_MAXCONPERSRV=1





# Split size i.e. size of each piece
# Possible Values: 1M-1024M
#
_MINSPLITSZ=1M


# Piece selection algorithm to use
# Available values are: default, inorder, geom
# default: selects piece so that it reduces the number of establishing connection, reasonable for most cases
# inorder: selects pieces in sequential order starting from first piece
# geom: selects piece which has minimum index like inorder, but it exponentially increasingly keeps space from previously selected pieces
#
_PIECEALGO=default



# Downloadmanager listfile
# You can use this value in _DOWNLOADER command. Escape with \${}: \${DLLIST}
#
# Default: /tmp/apt-fast.list
#
DLLIST='/tmp/apt-fast.list'


# Download command to use. Temporary download list is designed for aria2. But
# you can choose another download command or download manager. It has to
# support following input file syntax (\\t is tab character):
#
# # Comment
# MIRROR1\\tMIRROR2\\tMIRROR3...
#  out=FILENAME1
# MIRROR1\\tMIRROR2\\tMIRROR3...
#  out=FILENAME2
# ...
#
# Examples:
# aria2c with a proxy (set username, proxy, ip and password!)
# _DOWNLOADER='aria2c --no-conf -c -j \${_MAXNUM} -x \${_MAXCONPERSRV} -s \${_SPLITCON} --min-split-size=\${_MINSPLITSZ} --stream-piece-selector=\${_PIECEALGO} --http-proxy=http://username:password@proxy_ip:proxy_port -i \${DLLIST}'
#
# Default: _DOWNLOADER='aria2c --no-conf -c -j \${_MAXNUM} -x \${_MAXCONPERSRV} -s \${_SPLITCON} --min-split-size=\${_MINSPLITSZ} --stream-piece-selector=\${_PIECEALGO} -i \${DLLIST} --connect-timeout=600 --timeout=600 -m0'

# Download temp folder for Downloadmanager
# example /tmp/apt-fast. Standard is /var/cache/apt-fast
#
# Default: /var/cache/apt/apt-fast
#
DLDIR='/var/cache/apt/apt-fast'


# APT archives cache directory
#
# Default /var/cache/apt/archives
# (APT configuration items Dir::Cache and Dir::Cache::archives)
#
APTCACHE='/var/cache/apt/archives'


# apt-fast colors
# Colors are disabled when not using a terminal.
